Figure l'T is a wiring diagram for the embodi- -rnent illustrated in the other figures of the draw- I theink fed from different Width-wise orcolumnar portions of the fountain may be regulated from an ink control mechanismpositioned at; a distance from the fountain. Another object of the invention is; the provision of an, improved, inkingmechanism for rotaryprinting presses. havingv means for automatically increasing. or decrease ing the ink fed from different. portions of the fountain, the change in the regulation being automaticall-y and; selectively effected in accordance with the manually. selected setting of various control members-. The invention also. provides in a rotary perfecting printingwpress. having control means which may be varied in accordance with the; appearance of; the various columns; on the printed sheet, the control means. serving to effect proper adjustment of-the ink feeding means through a power operated member operating on the; ink feeding means in accordance with the setting of thecontrol members.

In accordance with the illustrative embodiment of, the invention whichv is shown as applied to. a rotary perfecting couple; of a newspaper press havingtwain-kingmechanisms, each of; which is capable of being adjusted throughout its length to supply diflierent quantities, of ink to.- thedifferent columns to be printed in accordance with the varying requirements oi'these columns; at one end of the press'is provided a support for a sheet which has been printed. Adjacent the support for the printed; sheet are two controls each of which. is provided with a plurality of control members equal to. the number of columns on each side of the sheet, and these individual; control members are preferably indexed and arranged in seq n e. in cc r ancewit t e Q-l ns o the pr n ed he t,

The inlg fountain is provided with a similar number of reg l nieam, ene al co pr s ng s ri i ad s g scr bea i g against th doctor blade to regulate the amount of ink remaining on the fountain roller to; be fed to the corresponding: positions of the printing plate. The adjusting screws are preferably arran ed in a series along the length of the fountain blade, and may be manually turned; to decrease or increase the amount of ink fed. Each of the screws is also provided with a gear, and along the series of screws extends a threadcd rod carrying i i-finger or rack for engagement with the gears in succes- Sim, as the finger or rack is moved length-wise of' the blade by rotation of the threaded rod. Means are also provided for selectively movin the finger or rack into and out of engagement with the gears as it passes them so that it may pass any or all of them idly or may engage and turn selective ones of 'the gears. AS the rack moves in one direction the gears are turned to increase the feed of ink while as the rack is reversely moved the gears are turned to decrease the amount of ink, thereby successively varying the adjustment of ink for each columnar portion of the ink fountain.

The control means includes a-number of individual control members each correspondingto a particular columnar portion of the ink fountain, and means are provided for controlling the operation of the moving rack or finger in accordance with, the setting of the various individual control members. Preferably a member senses the setting of the individual control members in succession, and in timed relation to the movement of the finger or rack across the ink fountain. Thus 7 the blade 3| may be moved toward or awa from.

imize the danger'of error, as well as to increase ders 29, plate cylinders 2 l, form rollers 22, ink distributing drums 23 and 21, distributing rollers 24' and 25, transfer rollers 26, ductor ro1ler 28 receiving ink from a fountain'roller 29 and transferring it perpendicularly to the distributing drum 21. Fountain roller 29 runs in the ink'fountain 30 at a relatively slow speed, and the quantity of ink remaining on the roller to be picked up by the ductor roller 28 is regulated by a doctor knife 3| which may be pressed toward the fountain roller 29 in varying degrees of pressure to regulate, with precision the amount of ink transferred tothe rollers and drums and thereby to the printing surface of the plates on cylinder 2|.

The various drums, rollers and cylinders are rotatably mounted in the ,frame'33, and certain of them are geared together while others are driven by frictionalcontact. The various rollers, drums and cylinders need not be described in furpages wide which has. been printed by the printing unit. .At' the top of the support is a clamp 41 V which may be conventionally numbered, the several numbers being located above the corresponding columns of the printed sheet 42 on the support; A source of light 43 may extend across the top of the printed sheet to facilitate the operators judgment of the quality of printing.

With the printed sheet 42 in position, the operator may readily determine by inspection that certain of the columns are being supplied with the proper amount of ink, others of the columns are receiving an excess of ink 'while still others of the' columns are receiving an insufficient amount of ink, and to correct this condition the operator should make the proper adjustment of the ink fountain in the shortest possible time, as such adjustments are normally made whil the press is operating at full speed and newspapers are being continuously printed.

The doctor blade 3| bearing against the fountain roller 29, extends from one end of the press I to the other and is rigidly secured to a blade support 45 by means of clamp bar 46 and screws 41, the mounting being such that the outer edge of the fountain roller 29. 7

Blade support 45 is provided alon its length with a series of screw threaded members 59' threaded into apertures in the support 35 with their lower ends bearing against the upper surface of the doctor blade 3| close to its free end. In the usual case one such screw 59 would 'be provided for each column printed, and thus in 7 of the screws 59 is provided at its upper end with a wing 53 bywhich it may be manually turned for adjustment independently of the other: columns. Means are provided for selectively and successively rotating each of the screws .55] first in one direction and then in, the other direction, to-vary thereto, and the gears Mare preferably all of the same size and are arranged in series in substantial alinement. Meshing each of the gears 54 is a double pinion 55 rotatably mounted by means of ther detail as they are of conventional construcv tion. Typically, the cylinders, drums and rollers may be of the standard four page width, and thus the printing plates on cylinder 2| would normally include thirty-two columns length-wise of the cylinder, each column bein arranged circumferentially of the cylinder. Such a press would normally print a web of paper four pages wide which would be slit into two longitudinal halves and cut to provide separate sheets, each sheet being sixteen columns wide.

Mounted on the frame 33 is a support 49 7 adapted to receive and hold a printed sheet tw 7 tion by their individual springs 59.

a stud 51 projecting into an upper face of the blade'support 45, and gears 55 are held in posi- Preferably the two gear faces of the gears 55 are of different size, the smaller meshing with the gear 54 so as to give a more minute turning and greater'megears 55. The hollow frame 64 and the shaft 69 V are so positioned and dimensioned that the lower 7 surface of the frame slidesv on the fiat marginal portion 65 of the blade support 15. The forward edge of the hollow frame isprovided; with gear teeth- 65 to form a short rack or finger member and the sliding movement of the frame 64 with reference to the shaft 60 is such that the teeth of rack 6-1 may: be moved into and out: of

engagement with the teeth-56 forming the lower gear portion of the gear 55.

Means are also provided for positively moving the rack teeth 66 into and: out of engaging position'with respect to the gears; 55. For this purpose a second shaft 58", parallel with shaft; 59. is also rotatably mounted" in the end wall; 61' and 6t. Throughout; its length shaft. 68. is: provided with a. slot-way Sh nto which fits, as; a. gear teeth, a rearwardly extending portion 6.4" of the hollow frame 64. By rocking shaft 68;. the rack. teeth 6.6 may be. moved into. and out of engaging. position with respect to the. several gears. 55.

' A- reversible motor H1- is-gearedito shaft 60, so as todrive the rack 61 in: either direction. At one end, shaft 6&. is connected to an arm 13- whieh is connected; by link 14- to solen id armature 1.5 o

it may be rocked to. and; from engaging position. A; spring. I1: is provided when normal-1y holding the rack. 61. in its inoperative position in which position it would move back and forth along the fountain without changing the adjustment. of any of the blade adjusting screws 50.,

As. the rack it! moves. across the fountain. from the leftto right-in. Figure 3-, solenoid l5. rocks the shaft. 68. properly timing the. rocking of shaft 68 with referenceto the travel of the threaded block 62,. any one or more selected screws 50 may be rotated. in a counter-clockwise direction to increase the amount of ink fed to their respective columns.

Likewise on the reverse rotation of the shaft. 6.0 causing the block 62, and rack 61. to travel from right to left, the timed rocking of 6,8 will cause any one. or more selected screws 50' to be moved in a clockwise direction thereby decreasing the amount of ink fed to the corresponding columns. 7

A cover [9 is conveniently provided on the upper surface of the support 45' enclosing the gears 54, 55, the rods 68 and 68 and the travelling rack member 6-1.

To insure more rapid and certain operation of the columnar adjusting means, a control member is preferably provided at an end of the fountain adjacent; to the sheet. support 41!; and is provided with a plurality of individual controls which are numbered or otherwise indexed: to their respective columns.

constructional. details and mode of" operation. of the control member is shown in detail in Figures 6 to 16, and illustratively comprises a rotatable control member 90 mounted on the upper end of a. vertical shaft 91 which is; mounted at one end of the press. and extending above an end of the fountain. Shaft 9| is; enclosed within a tubular housing 92, and is suitably journaled for rotation in an upper bracket 93 and a lower housing 94. At. itsv lower end shaft 9| is. provided with a worm gear 96. meshing. with. the worm. 9.1 on shaft 6.9 so that. the, rotatable member 9o makes one. complete revolution for each complete traverse. of the rack or fin er. 6.1..

Around its periphery the rotatabl member as is, provided with a cir ul r seri s of adjust n screws 9.8. each. having a squared head to which a key Hill may be fitted to turn them in either direction. As i'llustratively embodied thirty-two of the controlscrews 98 are provided, one, for each column-width of the ink fountain and: press, and

thes thirty-two screws: are; divided into; twoserifi of sixteen each, which are conventionally identified'by means of column numbers ml termed: on the upper surface or a. cover plate Hi2 secured to the upper surface. of member. by screws i194, and apertured: so that the square heads. 99, are accessible. through the cover plate.

Each of the screws. 981s provided. with a lower unthreaded portioni I 06 by which. the screw is 'rotatably mounted in a sli'dable block. t0?! mortisedi with a corresponding. slot to the: edge of the disk members 90, and a pin. collar [50:8 is; provided to hold the screws against axial movement. in their slide blocks. Thus. all of the screws 98 are held parallel to each other and to the shaft; 91, and ar mounted for sliding movement axially of the disk member 90; In each mortised slot is provided a spring pressed plunger I I0 bearing against a face of' the. block M1 and forcedtoward the block by compression spring- Ill, fri'ctionaily holding the. blocks H11 in any desired. position:

Cooperating with each screw 9&- isa rocker arm H 2 each rockerarm beingpivotally supported: on the control disk 99 by means of a bracket Hi3. Each of the rocker arms H2 near its outer end is provided with: a threaded opening N5- of considerably larger diameter than, but of the same pitch as screw 98, the lower portion of the threaded aperture H5 being above the pivot pin H6 so. that rocking-of the arm I I-Z'in one direction causes ngagement of the threads while rocking of the arm: in the other direction causes the threads to be released. The plunger PM is mounted: in the spring receiving aperture I21: and presses against the. inner head of each rocker arm- HZ to hold the threaded portion 1f5 normally in: engagement with the threads of screws 88 thereby normally preventing movement of the slide I01 except by turning of the screw 98. Each of the screws 98' may be turned in one direction other direction to lower the corresponding blocks,

and the blocks: Ht! are thus held in the desired positions so long as the rocker arms H2 are in their normal engagement. Figure 8 of the drawings shows the threaded portions. 98- and H5 in engagement with the corresponding block 1-01 moved to a relatively low position.

The feed end r23 of' each rocker arm H2 is provided with a nose engageable with a roller I24 freely rotatable and supported by a bracket F25 projecting inwardly from the frame member 93, and as the disk member 90 is rotated, he rocker arms I it are successivelylifted; to free the screws 98 sothat the blocks I 01' may be individually moved against the friction of plunger-s llll.

Switch means areprovided to be actuated by the slide blocks I01 when they" have been moved from their normal positions, and one such switch is provided to be operated byslide blocks I01 in a raised position, while another switch l'3l is to-be actuated by slide blocks I 01 in their lowered position, and means are also provided for varyingthe time during which the switches F30 and- I3 I are closed in accordance with the degree to which the slide blocks are moved away from to each other. Theupper face of-the helical rib I34 is designated as I36 and the lower .face is designated as I31. Switch I30 is provided with a beveled ended actuating plunger I40 arranged for movement radially with respect to. the disk member 90, and switch I3I is provided with a similar plunger I 4| the plungers I40 and MI being spaced from each other circumferentially of the disk 90, and also being spaced axially a distance equal tothe distance between the uppermost point of the surface I36 and the lowermost point of surface I31. so that in the normal position'of the slide blocks I 01 they may pass idly by each switch withoutv actuating either plungers I40 or I4I. a

As any one or all of the slide blocks I01 are raised, the upper surface I36 contacts with switch plunger I4I as the disk 90 rotates in a clock-wise direction past the stationary switch I3I mounted on the frame member 93, the time during which the switch I3I remains closed being determined by .the extent to which the particular block I01 was raised above its normal position thereby varying the time of engagement of helical surface I36 with plunger I4I. Likewise during the coun- ,ter-clockwise rotationof the disk 90, the time these means, together with releasingroller- I24 are positioned between the switches I30 and I3I and extending inwardly from the frame member 93. As embodiedihere are provided a pair of pivotally mounted fingers I43 and I44,.extending' V radially inwardly from their pivotal mountingon the pin I46. Fingers I43 and I44 are spaced apart and are so positioned that'their inner ends operate with-the inclined'or helical ribs I34 while the rocker arms I I2 are raised, and thereby force the slide I01 to its normal position. Each of the fingers I 43 and I44 is provided with a stop portion I48 preventing movement in one direction beyond the radial position, while the movement in the other direction is lightly resisted by means of a spring pressed plunger I39. The fingers I43 and I44 are blocked against movement in opposite directions 'So that the upper finger I43 is moved aside as the disk member 90 rotates in aicounter- V clockwise direction, and the finger I44 moves aside after the disk rotates oppositely; thereby clearing the b1ocks |01 completely only after the by the restoring finger' I43 as the disk 90 is moved inv a counter-clockwise direction preliminary to a later actuation of-the switch plunger II on the subsequent clockwise portion of the operating cycle. r V a Figure 1'7 of the drawings illustrates schematically the various circuit connections by which the parts are interconnected and supplied with power.

As illustrated-power is supplied from the three phase mains I50, I5I, I52 to drive the motor 10, and to cause actuation of the solenoid armature 15 in accordance with the setting of the various control screws .90, operation of the motor to rotate the control disk 90, and to move the actuating finger 61 in an ink increasing-direction is caused by, the push button I55,'while operation in the reverse direction is had by pressing the push button I56. A stop button I58 is provided to stop the mechanism at any point of travel of the finger 61. A limit-reversing switch I60 is provided at one end of the fountain to be actuated as the actuating finger 61 reaches the corto be actuated in timed relation with the passage of the control blocks I01 past the switches I30- and I3I, also in timed relation to the passage of the rack 61 past the various gears 56, thereby selectively and. accurately setting the various fountain columnar adjusting screws in acco -dance withthe setting of the various control screws 98. a

A multiple polerholding relay I10 is provided in the circuit and is moved to closed position by pressing the push. button I55, thereby placing the switch I30 in series with the winding of solenoid 15, and at the same time supplying current 'to the motor 10 through limit switch I60 so as to move the actuating rack or finger61 from left 'to right (Figure 3) or toward the limit'switch I60, thereby increasing the feed of ink-to selective columns.

disk 9 has made one complete cycle, thatis a v complete clockwise and one complete counterclockwise revolution.

Figures 10 to 15 illustrate the various positions .in the operation of the control means. In Figure 10, the helical surface I36 is approaching the switch plunger MI, and in the position shown .in' Figure 11 the switch plunger MI is depressed remaining depressed until the helical rib I34 has completely passed the plunger, the duration} of thisswitch closur depending upon the degree to which the rib I34 was raised.

In Figure 12 roller I24 has raised the rocker .arm nose I23 to release the screw,'and finger I43 has engaged the upper helical surface I36 to restore the block I1 to its normal central position.

7 Figure 13 shows the relation of the parts when this restoration has been accomplished.

rotate in a reverse direction to move the threaded As the threaded block 62 reaches limit switch I 60, this switch is opened and closes its other contact, thereby automatically reversing the motor 10 to move the actuating finger or rack 61 from right to left to efiect the desired decrease in the ink supply to selective columns. Motor10 continues to operate until threaded block 62 reaches limit switch I6I opening this switch, and thereby stopping the motor 10'. During thisreverse operation switch I3I was actuated by the selected control blocks I01 to cause actuation of the sole hold 15 as the actuating finger 61 passed the se-' lected columnar adjusting screws 50 thereby causing a decrease in the feed of ink to the various columns.

' A- stop push button I58 which is normally closed is provided so that the operation of motor 10 and the travel of the actuating finger 61 may be stopped at any point, and a reverse or ink decreasing push button I56 is provided which may be closed momentarily to cause the motor 10 to block 62 from right to left. of the'fountain.

The various circuit connections may be described as follows. Reversible motor 10 has its 'centerftap connected tomain I50 by conductor I88, while conductor I88 also provides one of the conductors through which current is supplied with the winding of solenoid 15; Main II is connected by conductor I8I to one contact of the normally closed stop button I58, as well as to one contact of the normally open holding relays I18, "I through conductor I82. Main I52 is connected through conductor I83 to the windings of holding relay magnets I13, I14, as well as to one of the normally open contacts of each of the holding relays. The contacts I85 and I86 of each of the holding relays form a reversing switch for supplying current to the conductors I81, I88 so that when holding relay I18 is closed motor 18 operates in an ink increasing direction, and operates in an ink decreasing direction when the holding relay I1I is closed.

Normally the parts are started in operation by pressing push button I55 and thereby current is supplied from main I'5I through conductor I8I., stop button I258, conductor I89, limit switch I68, conductor I98, contact I9'I., conductor I92, contact I93, conductor I94, which completes "the circuit through magnet winding 11.3, conductor I83 to main I52, thereby causing closure of the holding relay I18. As motor 18 drives shaft 68 actuating finger 61 is moved from left to right of :the fountain and the gear 96 and the :control member 98 are moved in a countereclockwise direction.

Any of the control blocks I 81 whichh'ave been raised above their 'normalposition cause closure of switch I 38 for periods of varying length in timed relation to the passage or the actuating finger past the gears '56 andtheir respective adjusting screws 58, the actuating finger being moved toward and from the gears by operation of the solenoid '15. Solenoid 1-5 is connected from conductor I88 through its winding to conductor I96 through switch I38, conductor I91, contacts I98 held closed by the holding relay I18, -conductor I99 which is connected to main-I52 through conductor I83. 9

When the traverse of actuating finger '61 has been completed, limit switch [60 is opened and moved into contact with its other contact 208 thereby establishing a circuit from main 'I,5'I, conductor 'I8I, stop button I58, conductor 189, contact 288, conductor 28'I winding I14, conductor I83 and main I52 thereby energizing the holding relay "I to move 'its'contacts to closed position. Closure of relay I1'I causes motor 18 to "be reversed, thereby moving the control finger 61 and the gear 96 and control member 98 the opposite direction causing switch I3I to be periodically closed. As this switch is closed, current is supplied from main I52 through con- .ductor I83, conductor I99, contact 283 conductor 284, switch I3I, conductor I96, the winding of solenoid 15 and conductor I88 to main I58.

'Motor 18 continues to run in the reverse direction effecting the selective decrease in -columnar supply of ink until threadedrblock 62 opens switch I6I, thereby interrupting the supply of current to'the magnet winding I14, and bringing the mechanism to rest.

Stoppage of the mechanism at any point in its travel may be secured by opening push button I58, thereby interrupting the supply of current .to the holding coils of relays I18 and HI.

With the mechanism in any intermediate position, :its operation in :the reverse direction may bestart-ed byclosure of push button I56 which causes holding relay ;I1I to be energized-in the same manner as by limit-reversing switch I68 and contact 288.

Contact 285 serves to shunt push button I55 when holding relay I18 is closed and. similarly contact 286 shunts push button I56 When hOIding relay I1I is closed, thereby preventing accidental actuation of either holding relay while the other is'heldclosed.

In order to prevent excessive movement of any of the adjusting screws 58, their gears 54 are preferably mutated as at 54, thereby allowing them to be turned approximately three-quarters of a turn under the control of the control member .9.8. Whena greater adjustment in either ink increase-or ink decrease direction is required, the

individual screws or any one of them may be turned. by their wings 53 so as to bring the teeth of the corresponding gears 54 into mesh with pinions 5.5.

As illustrativel-y shown in Figures 18 and 19 of the accompanying drawings, the invention may be applied to the inking mechanisms of a plurality of printing units, the several inking mechanisms being selectively controlled by a single ersing vmeans and columnar adjusting means may beidentical with that described above and shown in Figures 1 to 5.

Near one end of the press is provided the res versible motor .18 which serves to traverse .oneor another of the dogs 62, the selection of the .dog to be traversed being under control of the mannal control device :2 68. Motor 18 drives shaft 262 in vone direction or another through reduction ,gearing 2.64, the direction-of ,rotationof the motor being controlled by ,push buttons J55, I56 and "I58 accordance with the circuit vshown .in Figure l7. Shaft .262 carries a worm '91' by which the Worm gear 96 of the control means 90 issimilarly driven in one directionor another, as :previouslydescribed. Shaft 262 is connected to-drive I the dog traversing shafts 68 through the miter ,gears266 so that all of the dogs 62 are traversing back and .forth across their respective fountains in uniform and timed relation with the rotation of ,theshaft SI of the control means 98,

For moving the dogs 62 selectivel into and out of engagement with the pinions '56 each of the inking mechanisms is provided with its individual solenoid winding 215 which serves to actuate the corresponding armature 15 to rock "the selective oneof the shafts 68.

The manual control means for selecting the inking mechanism to be adjusted from the single control member 98 comprise a number vof push buttons 2-18-each of which carries a movable contact 21 I adapted to bridge contacts 212 thereby closing one of the circuits between conductors I88 and I96 and through the corresponding solenoid winding 215. While these manual control means 268 ,may be of-anydesired'form, they are preferably of the general type shown in .Figure 19 and include .means for .releasably maintaining the selected contact 211 in circuit closing position until another push button 1218 has been moved. Each of the push buttons 21!] is provided with a'compression spring 274 tending to move the push button to open circuit position. A stop 215 limits the travel of the pushbutton rod, and 7 the contact 211 is mounted on the rod and insulated therefrom by insulation 216, A holding casing 28! and is provided with key hole apertures;282- through which the push button rods extend. 'A spring 283 serves to bias the plate 280 towards locking position and the small conical members 284 'carriedbyeach push button rod serve'to earn the plate to release position as well as to hold the selected push button in closed position. As shown the second push button is closed and remains closed until another push button is. selected and moved to closed position.

jThis movement automatically releases the second push button and the newly selected push button remains in closed position until the next selec tion is made. The several solenoid windings 215 are connected with conductor I96 b the common branch conductor 286, while the individual branch conductors 2%, 292, 293, 294, 295 and 295 ponnect the individual solenoids through their respective push buttons 210'to the conductorl80; a

When the pressman. sees that a particular unit requires adjustment of its inking mechanism he sets the control screws 98 in accordance with the requirements of that unit and then pushes the appropriate push button 210 and thereafter the appropriate direction button I55 or 156. The motor rotates to drive all of the dogs B'Zacross their respective fountains, but only the dog corresponding to the particular unit to be adjusted is rocked into and out of'contact with its pinions plate 280 is slidably mounted in the ends of the arranged a line serieafa motor driven member movable along theseries, means, for automatically moving the member into and out of actuating contact with the adjusting means sam nieinber automatically increasingthe feed of by movement in: one direction and decreasing' the "feed of ink in the other direction in a preselected amount, and means for automatically reversing the motor driven mean's'at the end-of its movement in one direction. a V
